Added spring.cloud.function.definition property which is used by FunctionRegistry as a supplement instruction to resolve nameless lookups.
It is used by web module to map single or multiple (composed) functions to the root path (/)
Resolves#247
This is useful for example if the user is taking care of the
functional bean registration in some other way, and still wants to
use spring.functional.enabled=false to control that.
Resolves#233
Happens when HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTES is null
Can be seen when using spring-boot-starter-actuator with a scanned function
The path is null because the request wrapped by the WebMvcMetricsFilter is unmodifiable,
so setting the attribute in AbstractHandlerMethodMapping#handleMatch has no effect
User can now provide a Function or an ApplicationInitializer. Also
the initializer can create a FunctionRegistration with the handler
name instead of a bean with the handler name. Better control of
input and output types that way.
Fixes gh-231
Added support for function parameter type Collection
Updated both Jackson and Gson mappers
Defined a new toObject() operation on JsonMapper and deprecated the old
Resolves#210
We want the default application type to be REACTIVE if webflux is
present (formerly it was NONE). In AWS and Azure we also want
the webflux beans to be switched off in a "lite" application
context (formerly they were unconditional).
User can run a minimal HTTP app using an app that is a Function
or an ApplicationContextInitializer. Can also test using
@FunctionalSpringBootTest in place of @SpringBootTest.
Add some tests and documentation for functional beans
Make server.address configurable
MVC and Webflux share some common business logic
so it makes sense to put them in the same module.
Also simplifies the MVC code, removing the custom argument
and return value handlers.
Weed out unecessary method param
Unignore some tests
